Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single fixed filter layer is used, then the device structure is simple, but particles of different sizes cannot be separated effectively
Solution Approach 1:
The patent employs deformable membrane structures that can dynamically change their shape and pore configuration in response to pressure differentials. This allows the same filter structure to adapt to different particle sizes by adjusting the membrane deformation state, thereby achieving multi-size particle separation without requiring multiple fixed filters with different pore sizes.
Solution Approach 2:
The patent changes the physical state and configuration parameters of the membrane structure through pressure control. By adjusting pressure differentials across the deformable membrane, the effective pore size and membrane configuration are modified, enabling the system to separate particles of various sizes using a single adaptable filter structure.
2Device complexity
If a single fixed filter is used, then the device is simple, but collecting separated particles is difficult
Solution Approach 1:
The deformable membrane structure dynamically opens and closes pathways based on pressure differentials. After particle separation, the membrane can be deactivated to open collection pathways, allowing trapped particles to be easily flushed out and collected. This dynamic operation simplifies the collection process compared to fixed filters requiring complex mechanical removal mechanisms.
3Productivity
If deformable membrane structures are used, then particles of different sizes can be separated and collected efficiently, but the device complexity increases
Solution Approach 1:
The deformable membrane structure utilizes pressure differentials generated during normal fluid flow to automatically deform and separate particles. The membrane responds passively to flow conditions without requiring external actuators or complex control mechanisms, thereby achieving efficient particle separation while minimizing the addition of complex control systems.
